摘要： 采用氰尿酰氯和三溴化硼为原料, 金属钠为还原剂, 通过化学还原法在450℃合成了B-C-N化合物. 利用X射线衍射(XRD), 透射电子显微镜(TEM), 选区电子衍射(SAED), 电子能量损失谱(EELS)和傅立叶变换红外光谱(FTIR)对合成的样品进行了表征. 分析结果表明, 所合成的B-C-N化合物具有六方多晶结构, 其成分为B0.5C0.07N0.43.

关键词: 六方B-C-N化合物, 化学还原法合成, XRD, 电子能量损失谱

Abstract: Hexagonal B-C-N compounds were successfully synthesized by using hydrogen-free 1,3,5-trichlorotriazine and boron tribromide as reactants and metal sodium as reluctant through a chemical reduction synthesis method at 450℃. The synthesized sample was characterized by X-ray diffraction (XRD), transmission electron microscope (TEM), selected area electron diffraction (SAED), electron energy loss spectroscope (EELS) and Fourier transformation infrared spectroscope (FTIR), respectively. The results indicate that the synthesized B-C-N compound is polycrystalline with hexagonal structure and its composition is B0.5C0.07N0.43.

Key words: hexagonal B-C-N compound, chemical reduction synthesis method, X-ray diffraction, electron energy loss spectroscopy
